8 Claims.

This invention relates to a mounting for rear vision mirrors and more particularly to a mounting for a prismoidal rear vision mirror whichreflects a primary and secondary image, the mirror being movable by the driver of the automobile to reflect the primary bright image from the highly reflective coating of the mirror during.

in connection with the usual plane rear vision mirror, the mounting permitting the mirror to be manually swung to an inoperative position to avoid the reflection of glaring headlights into the eyes of the driver and to be manually restored to its operative and properly adjusted position after the objectionable condition has ceased to exist.

The principal object of the invention is to provide a simple and inexpensive mounting for a rear vision mirror which permits the mirror to be freely adjusted about its vertical and horizontal axis, and also leveled, to suit the height and position of the driver, and at the same time permits the manual movement of the mirror, within a controlled are, without disturbing the said adjustment of the mirror.

Another object of the invention is to provide simple means for limiting the movement of the mirror in said are so that the driver has merely to move the mirror through said are to one of two extreme positions to obtain the primary bright or secondary dull image when the rear vision mirror is a prismoidal mirror, or to move the mirror from its operative to an'inoperative position when the rear vision mirror is a plane mirror.

Another object of the invention is to provide a handle for so moving the mirror through said are so that the movement of the mirror is effected by'the simple expedient of moving the handle to one of its two extreme positions.

Another object is to provide such a handle for angling the mirror through such controlled arc I in which the handle and the parts actuated by it are wholly dissociated from the means for leveling and adjusting the mirror to meet any particular driving conditions whereby the manipulation of the handle cannot disturb such ad- 'justment.

Another purpose is to provide .such a handle which is convenientlydisposed and of such form as to be readily moved to either of. its extreme positions without interfering with the driving of the car.

Another aim is to provide such a mounting which,-in addition to being inexpensive in construction, is simple and'neat in appearance so as to provide an automobile accessory which is attractive in appearance and in harmony with the other interior fittings of the automobile.

Another object is to provide such a mounting which is free from vibration so as to avoid disturbing blurring of the image by vibration.

Another aim is to provide a simple means, where a prismoidal mirror is employed, for encasing the prismoidal mirror in which the danger of breaking the relatively expensive prismoidal mirror either in the course of producing the rear vision mirror assembly or while in service is avoided.

Fig. 13 is a fragmentary view similar to Fig. 9 and showing a further slightly modified form of the invention corresponding generally to the form illustrated in Figs. 8-12.

The invention is shown as embodied in. a mounting for a prismoidal mirror which is indicated generally at i0, although it will be understood that the mirror can also be used to support a plane mirror in which case the handle control as hereinafter described is merely used to move the mirror from an operative to an inoperative position and vice versa. The prismoidal mirror i is shown as made of a generally rectangular plate ofglass H which is ground so that the vertical axis of its rear planar face i2 is at an angle to the vertical axis of its front planar face i3, but the horizontal axes of these faces are parallel. The mirror I0 is thereby wedge shaped in vertical section and is arranged with its thicker part at its upper end. The glass plate ii is provided on its rear face i2 with a coating it .of reflective material, this coating being preferably of a highly reflective metal, such as silver,

in view of the fact that a dulled effect is obtained through using the secondary image reflected by the front face it of the glass panel M. This glass panel ii is also shown as being beveled around its edges, the beveling around the upper part of the mirror being at a lesser angle than the bevcling around the bottom of the mirror. The glass plate is also shown as being rounded at its corners to provide a mirror of pleasing shape.

The mirror is held by a metal backing plate or case it, the edges M of which conform to the edges of the mirror plate ii and these edges being bent around the beveled edges of the glass plate ii, as best indicated in Fig. 2, these bent edges thereby holding the glass plate against forward displacement. In order to hold the glass plate ii against rearward displacement the fair-- ror plate ii is backed by a paper protecting sheet 22 and a metal liner plate 23 is arranged within the case 20, the edges of this liner plate 23 bearing against the rear face of the paper protecting sheet 22 at its edgesand the central part of the metal lining plate 23- bearing against the inner face of the case 20, as best shown in Fig. 2. To permit of adjusting the mirror. about its vertical and horizontal axis to suit the height and position of the driver, and also to permit of ajaaaois I punched forwardly from the metal liner 23 and bent over the edge of the spring strip 29. It will be seen, assuming the stem of the ball 25 to be held stationary, that the driver can grasp the edge of the mirror case and swing it around both its vertical and horizontal axes to obtain a clear view through the rear window of the automobile and can also level the mirror after it has been so adjusted. This adjustment will vary with each individual driver and it is one of the objects of the invention to preserve this adjustment when the mirror is swung to reflect either its bright image or its dull image into the eyes of the driver.

With the prismoidal mirror as shown it will be seen that a primary and a secondary image is reflected. The primary image is reflected by the highly reflective coating Id of the rear face i2 of the glass mirror panel ii. The secondary image is reflected by the polished front face it of the glass mirror panel i i. The vertical axes of the rear and front faces l2 and I3 of the glass mirror panel ii are arranged at such angle that the angles of incidence and reflection of the front face it are greater than the corresponding angles of the reflective coating M so that the primary bright image .is. reflected above the secondary dull image at the eye of the driver. To permit of using either of these images means are provided for rotating the mirror through a vertical angle so as to bring either the upper primary image or the lower secondary image to the eyes of the driver.

For this purpose the stem 28 of the ball 25 is secured to a fork 3b, the arms 38 and 81 of which project rearwardly parallel with the axis of the stem 25. The inner vertical faces of these arms 26, S'll are arranged parallel to each other and. these arms are provided with alining openings 88, as adapted to receive a pivot pin ill, the hexagonal head of which is recessed into the opening iitl. This pivot pin is held in position by a screw leveling the mirror after having been so adjusted formed to provide a seat 28 engaging an annular portion of the rear surface of the ball 25, the stem 28 of this ball extending through the opening 21. The ball 25 is held in firm frictional engagement with its seat 28 by a plate 29 made of spring metal and formed to receive the front end of the ball 25. The ends of this plate 29 are sprung rearwardly and held by six fingers 30 (it which is screwed into a threaded bore provided in the pivot pin til and the round head of which is recessed into the opening 38.

Any'suitable means can be provided for securing the fork 36 to the end of the stem 26 and as shown this stem is provided at its rear end with an annular enlargement 53 having a rear flat face which fits against a correspondingly forwardly facing flat face of the fork 35. A concealed screw 46 extends forwardly from between the two arms of the fork 35 through an opening provided at the front end of the fork 35 and into a threaded axial opening 65 in the stem 26 of the ball 25. The stem 26 is prevented from turning relative to' the fork 35 by providing a fiat 4B in the upper part of its enlarged annular portion 43, this flat 4'8 being engaged by a finger M provided in the upper front part of the fork 35. The fork is supported by a head bar attaching stud 50, the shank 5| of which is threaded to screw into the head bar 52 of the automobile, the stud being held against turning by;the tightening of a nut 53 against the head bar; The stud 50 is formed'to provide an enlarged annular head 54 provided with an axial opening 55, the horizontal axis of which is arranged at right angles to the axis of the shank of the stud 50. The head 54 is formed to provide opposite parallel faces which frictionally engage the inner parallel faces of the arms 36 and 31 of the fork 35, the pivot pin 40 extending through the opening 65 in the head 54 andv the frictional engagement between the corresponding flat faces of the stud i! being from, although it will be understood-that this handle could. extend upwardly from thefork if it were desired to manipulate the handle from the top instead of'the bottom of the mirror. This handle 56 preferably curves rearwardly to permit the free adjustment of the encased mirror around the ball 25 and its lower end 51 is extended forwardly to a transverse bar 58 which is preferably arranged immediately adjacent the lower edge of the encased mirror panel and substantially parallel therewith. It will therefore be seen that to swing the mirror so as to reflect the secondary image it is merely necessary for the operator to pull the cross bar 58, thereby swinging the fork 35 counterclockwise, as viewed in Fig. 2, around the axis of the pivot pin 40 so as to swing the lower edge of the mirror panel In toward him and bring the secondary image into hisview. This position of the partsis illustrated in Fig. 2. Conversely, during daytime driving when the driver desires the primary image he pushes on the bar 58 thereby to swing the fork 35 clockwise about the pivot pin 40,- as viewed in Fig. 2', so as to bring the primary image reflected by the coating 14 into his view. I

The movement of the fork 35 around the axis of the pivot pin 46 which is necessary to bring either the primary or the secondary image into the eyes of the driver of the automobile is about 3 In order to facilitate the adjustment of the mirror positive stop means are provided for restricting the rotation of the fork 35 around the pivot pin 46 to this 3 /29. For this purpose the stud 50 is provided with a collar 60, one side of which is provided with a laterally extending lug 6|, this lug being formed to provide a notch 62. The corresponding arm 31 is formed to provide a finger 63 which extends into the recess 62. The finger is slightly smaller, in its direction of rotation, than the notch 62 and it will therefore be seen that a limited play is provided between the notch and the finger, this play permitting El /2 of rotation of the fork 35 into vertical plane. By this means it will be seen that no care need be exercised by the driver in'adjusting the rear vision mirror to provide either the primary or secondary image, it being merely necessary for him .to push or pull the 'cross bar 58 of the arm 56' within thelimit set by the fit of the finger 63 within the notch 62. I

To insure the maintenance of the proper set position of the mirror panel, regardless of whether it is set by the manipulation of the handle 56 to reflect either the primary or the secondary image into the eyes of the driver, it may be desirable to bend the attaching stud 50 in the manner shown by dotted lines in Fig. 3.

"As there shown, the stud is bent so as to be generally coincident with the line of vision of the driver and hence so that its pivot pin 40 is arranged at right angles to the line of vision of the driver instead of parallel with the head bar 52, as illustrated in full lines. With the stud 50 bent in this manner there is no tendency for the angling of the mirror through the handle 56 to alter the setting of the mirror panel on the ball 25 as by causing the right hand side of the mirror to drop slightly out of line as might be the case if the stud 50is straight, as indicated by full lines in Figs. 1-4.

As a matter of practical manufacture it may be difllcult to produce prismoidal mirrors with sufficient accuracy to match, exactly, the 3% movement permitted by the finger 63 in the notch 62." Under such circumstances the notch 62 would be proportioned to provide, say, a 334 movement of the fork 35 and an additional ms 65 is providedon the opposite side of the neck 66 from th lug 6!. This lug is then provided with a notch 66, as shown in Figs. 3 and is similar to the notch 62 except that it is slightly larger. Thus, when the finger 63 is arranged in the notch 62, as illustrated in Fig. 3, the fork 35 would have, say, a 3%? movement. If, through a' factory screen test, it is determined that the mirror has a slightly greater movement, the stud 50 would be reversed during assembly, as illustrated in Fig. 4, so that the finger 63 would engage the notch 66 instead of the notch 62. This notch 66 is slightly larger and would afford, say, a 3% movement of the fork 35 around the pivot pin 40. By this means an adjusting of onehalf a degree is provided to compensate for any irregularities in the production manufacture of the prismoidal glass panel II. The difference in the angle of adjustment permitted by the parts arranged as in Fig. 2 and the parts as arranged in Fig.4 is illustrated by the broken lines a--a and b-b, respectively, in these figures, the angle bb being greater than the angle a-a. It will be understood that as illustrated these angles are very much exaggerated:

It is apparent that instead of providing two notches 62 and 66 on the stud 50 and a single finger 63 on the fork, it is possible to provide two fingers on the fork engaging in one notch in the stud. Such a slightly modified construction is illustrated in Figs. 5-7 in which each arm of the fork is provided with a finger 10, 1|, these lugs being each engageable with a recess 62a provided in the stud 50 in the same manner as with the recess 62 in the form of the invention shown in Figs. 1-4. The finger 1| is slightly smaller than 'Fig. 7, the mirror will have a comparatively slight degree of movement. It will therefore be seen that the form of the invention shown in Figs. 5-7 provides an ability of adjustment in the manufacture of the mirror assembly'to compensate for slight variations in the manufacture of the prismoidal glass in the same manner as in the form of the invention shown in Figs. 1-4. Since in other respects the constructions are identical the same reference numerals have been applied. r

In the modified form of the invention illus-.

'trated in Figs. 8-12, the prismoidal mirror is identical with that shown in Figs. 1-7 and hence the same reference numerals have been employed.

This prismoidal mirror, in the form of the invention illustrated in Figs. 8l2, is shown as held in a metal backing plate or case 80, the edges 8| of which conform to the edges of the mirror plate II and these edges 8| being bent around the beveled edges of the glass plate H, as best illustrated in Fig. 9, these bent edges thereby holding the glass plate against forward displacement. In order to hold the glass plate ll against rearward 4 which displacement the mirror plate I I is backed by a paper protecting sheet 82, and a metal liner plate 88 is arranged within the case 88, the upper edges of this metal liner plate 88 bearing against the rear face of the paper protecting sheet 82 at its edges and the central part of the metal liner plate 88 bearingagainst the inner face ofthe case 88,

as best shown in Fig. 9.

To permit of adjusting the mirror about its vertical and horizontal axis to suit the height and position of the driver, and also to permit of leveling the mirror after having been so adjusted, the encased mirror, as in the form of the invention shown in Figs. 1-7, is shown as carried on a #ball 88 having a'stem 88. The ball 881s, however, substantially larger' than the ball 28 supporting the form of the mirror shown in Figs. 1-7. To seat against the ball 88, the back of the case 88 and its'metal liner plate 88 are formed togpro- .vide an opening 81 and the metal surrounding this opening is formed to provide a seat 88 engaging an annular portion of the rear surface of the ball 88, the stem 88 of this ball extending through the opening 81. The ball 88 is held in firm frictional engagement with its'seat 88 by a plate 88 made of spring metal and formed to receive the front end 'of the ball 88-. The ends of this plate 88 are sprung forwardly and held by six fingers 88 punched forwardly from the metal' liner 88 and bent over the edges of the spring strip 88. It will be seen that the encased mirror can be adjusted about the ball 88 to suit the height and position of the driver in the same manner as with the form of the invention shown in Figs. 1-7. In addition, however, both the metal case 88 and the metal liner plate 88 are slotted. as indicated at 8|, this slot extending upwardly from the opening 81 for the ball stem.

- To permit of shifting the mirror to reflect either the primary or the secondary image to the,

eyes of the driver without disturbing the adjustment of the mirror about the ball 88, the stem 88 or the ball is formed to provide an integral, flat,

vertical tang 88 of round form. This tang is provided with a coaxial opening 88 and is also provided with a flat tail piece 81 having a. transverse I the opening 81 and hence it will be seen that the ball 88 can be drawn into engagement with the seat 88 surrounding this opening. Thereafter the spring metal plate 88 can be positioned and stressed so that its edges can be secured by the fingers 88 and the glass mirror plate can be positioned and the edges of; the case 88 crimped around its margin. It will be seen that by making the ball 88, stem 88, tang 88, tall piece 81;

faces'of the tang v88 by a pivot pin it? which passes through opening I88 provided in. the Jaws I88 and through the opening 88 in the tang 88. The head of this pivot pin bears against one of the Jaws I88 and pressure is exerted against the Jaws by a screw E88 which is screwed into a threaded bore provided in. the pivot pin I81 and the head of which bears against the other jaw I 88. The bifurcated stud MP8 is held in position in the head bar 82 by a locking nut I'I8.

In order to limit 'the movementof the mirrorassembly around the axis of the pivot I81 to the extent required to bring the primary or the secondary image to the eyes of the driver, a screw III is screwed into a threaded opening provided in one of the Jaws -I88 and extends through the opening 88in the tall 81 and into the opposite law I86. The part of the screw III which extends through the opening 88 in the tail piece is shown as being of tapering form so as to permit of adjusting the efiective'size of this pin by screwing it in and out to a greater or less degree. The

- size of the opening 88 in the tail piece 81 is such erably, by die casting, as a single integral metal part, it is apparent that the parts of this casting must be so proportioned as to be capable of being inserted or threaded through the opening 81 from the front of the metal case 88 and metal liner plate 88 before the glass mirror panel II is crimped in place, For this purpose thelength of the cross bar I88 is limited so as to be capable oi being passed through the opening 81, this being eil'ected by inserting first one end of the cross bar through the opening until the handle 88 engages one side of this opening and then swinging the other end of the cross. bar I88 through this opening. The handle 88 is then threaded through the opening 81 until the tail piece 81 is encountered. This tall piece is of less thickness course, u

- as to provide,- say, a 3% degree movement of the mirror panel I8, this mirror being tapered to bring either its primary or secondary image to the eyes of the driver. If in the production grinding oi' the mirrors it is inexpedient to grind the mirrors to produce exactlythis eflect,.the mirrors can be subjected to a factory screen-test and the screw III adjusted toprovide a slightly greater or slightly less amplitude of movement as the particular mirror may require.

It is'apparent that the tail piece 81 is not essential to the invention although itis desirable in thatit permits the hole greater distance from the axis of the pivot pin I81 than ii this hole were provided directly in the tang 85. The further this hole can be disposed away from this axis, the less the necessity, of course, for extreme accuracy in the shape of the hol so that theuse of the tail piece 81 is preferred. However, as illustrated in Fig. 13, the piece 81 can be eliminated and the hole 88a for the reception of the tapered pin I I la can be provided directly in the tang 88a, the parts in the form of the invention shown in Figp13 otherwise conforming exactly to the form of the invention illustrated in Figs. 8-12. With the elimination of th tail 81, as illustrated in Fig. 13, it is, of

ni iecessary to provide the slot 8| in the mirror case 88 and inner backing plate 83, as the only purpose of this slot is to permit the tail piece to be passed through these parts in assembling the mirror as'previously discussed.

From the foregoing it will be seen that the I to to be located a 2,825,615 present invention provides a mirror in" which a handle is provided for swinging. the mirror panel to reflect either the primary or secondary image into the eyes of the driver, where the mirror is of prismoidal form, without in any way affecting the adjustment of the mirror to suit the particular driving conditions. It will also be seen that this movement of the mirror is easily effected-and is positively limited so that the driver. need only push or pull the lever to its extreme position to obtain either of the images. It will further be seen that the instrument as a whole can be produced at low cost, which is an essenlimiting said oscillation of said mirror panel around the axis of said pivot pin.
